Drag and Drop btw WinForm and WPF control

Question

hi.. group,

 

I have a wired situation. I tried to do drag and drop from a WinForm control to WPF control.

 

In WinForm control, my code is:

    myUserControl.DoDragDrop(myData, DragDropEffects.Move);

 

On WPF Control, I tried to get the data:

  

   e.Data.GetData(typeof(MyData));

 

I got an exception saying: HRESULT_FAIL from some COM, blah blah blah..

 

I can use e.Data.GetDataPresent(typeof(MyData)) without any problem.

 

Can somebody give me a hint how to fix this problem?

 

thanks.
